Hemming (1967) stated:-

On observing that the generic name Gastrochaeta Holland, 1894, was invalid under the Law of Homonymy, I decided, in agreement with the late W. H. Evans, that the publication of an avowed replacement name would be undesirable, for, if that course were to be taken, the genus bearing the replacement name would, like Gastrochaeta, have as its type-species the rare and little-known species Gastrochaeta mabillei Holland, 1894. We decided therefore that the best course would be to establish a new nominal genus expressly based on the characters given by Holland on the second occasion on which he dealt with that genus (that is in 1896, Proc. zool. Soc. Lond. 1896 (1) : 37) and to designate as the type-species some better-known species exhibiting the same generic characters as those found in Gastrochaeta mabillei. It was in accordance with the arrangement so agreed upon that I established the nominal genus Mesa, having as its type-species the well-known species Hesperia meza Hewitson, 1877.

Cowan (1970: 47) stated:-

GASTROCHAETA : the third para should read - In the former paper Holland attributed the generic name to Mabille, believing it had already been published. He therefore gave no diagnosis and described only his new species Gastrochaeta mabillei Holland. This served to establish the generic name. In the 1896 paper Holland gave a full diagnosis for the genus, with a figure of the wing neuration of the male Hesperia meza Hewitson with which species the diagnosis entirely accords. Holland then explained his earlier misunderstanding, and how it meant that G. mabillei had to be the type-species rather than the much better known meza. See also: below under Meza Hemming.

Cowan (1970: 51) stated:-

MEZA - The anomaly that this genus is nominally diagnosed for a species other than the type is explained in the entry above for Gastrochaeta.

The higher classification used here follows Lamas (2008).
